Editing Battle of Vauchamps (section)

==Pursuit==
With the Coalition forces now in full retreat, Marmont received orders to aggressively pursue the enemy, knowing that he could count on his two infantry divisions, plus that of Leval, as well as on the support of General [[Antoine Drouot|Drouot]]'s Guard artillery, on [[Etienne de Nansouty|Nansouty]]'s Guard cavalry on his right and on [[Emmanuel de Grouchy|Grouchy]]'s two cavalry divisions on his left. Following Marmont at a short distance were further reinforcements, two Guard infantry divisions (Friant and Curial) under the command of Marshal [[Michel Ney|Ney]] and with them was [[Napoleon]] himself.<ref name="Mir65"/> Napoleon was followed by an additional "Young Guard" division, under General Meunier, which the Emperor had taken with him when he left [[Château-Thierry]] early that morning.<ref name=Pigeard886/>

The French cavalry had been hindered in its movements by the broken terrain and thus far unable to really bother Zieten's infantry squares. Consequently, Blücher was able to lead an exemplary retreat up to Fromentières and Janvilliers. However, once past these villages, the terrain became flat and even, proper for cavalry action, and now, with the increasingly aggressive action of the enemy cavalry against his flank and rear, Zieten and his brigade became increasingly isolated. Grouchy, with the divisions of Doumerc and Saint-Germain was now boldly menacing Zieten's right, while on his left, the Prussian general saw Nansouty's Guard cavalry ([[Louis Marie Levesque de Laferrière|Laferrière-Levesque]]'s division, plus the four service squadrons, under [[Charles, comte Lefebvre-Desnouettes|Lefebvre-Desnouettes]]).<ref name=Pigeard887/><ref name=Mir65/> Zieten's brigade was finally cut off from the rest of the army and charged violently by Grouchy's [[cuirassier]]s, who broke the infantry squares and took no less than 2,000 prisoners, with the rest of the brigade routed.<ref name=Pigeard887/>

Abandoning his position at Fromentières, where Marmont's infantry had just begun to irrupt, Blücher ordered the continuation of the retreat towards Champaubert and Étoges, with Kleist's Corps on the left, south of the road and Kaptzevitch's Corps on the right, north of the road. Again taking advantage from the flat terrain, Grouchy was able to advance rapidly and fall onto the rear of the Coalition infantry squares, which were now slowly withdrawing in [[Echelon formation|echelon]] and efficiently using the terrain to take shelter from the artillery bombardment. With night approaching and their retreat towards Étoges now barred by enemy cavalry, the Prussian squares began to lose cohesion. Spotting this weakness, Grouchy, who had been reinforced by [[Étienne Tardif de Pommeroux de Bordesoulle|Bordesoulle]]'s division, energetically launched his three divisions against the Coalition squares, dispersing a number of them, with these men fleeing in disorder to take refuge in the Étoges forest. The old Blücher, who had been bravely exposing himself to great danger in order to boost the morale his men, was almost taken prisoner, together with his chief of staff, [[August Neidhardt von Gneisenau|Gneisenau]], Generals  Kleist, Kapsevitch and [[Prince Augustus of Prussia]].<ref name=Pigeard887/><ref name="Mir66">Mir 2009, p. 66.</ref>

Only just escaping capture, Blücher crossed the forest of Vertus and took up positions at Étoges with Prince Urusov's division, which had been left there in reserve. Russian General Udom, with 1,800 men and 15 cannon, was instructed to cover the position, by occupying the park at Étoges. Udom's men were exhausted after the long retreat and fighting and, seeing that night had fallen, thought themselves in safety. However, Doumerc's cuirassiers, formed unseen in the night, surprised these men and a single charge was enough to send the panicked men fleeing. Prince Urusov, 600 men and eight artillery pieces were captured during this action, with the French sailors' regiment from Lagrange's division subsequently entering the village of Étoges. Blücher abandoned this position too and made a hasty retreat towards [[Vertus]] and Bergères. He then opted for a speedy night march and the next day he managed to bring his remaining men to [[Châlons-en-Champagne|Châlons]], where he was joined by [[Ludwig Yorck von Wartenburg|Yorck's]] and [[Fabian Gottlieb von Osten-Sacken|Sacken's]] corps.<ref name=Pigeard887/><ref name=Mir66/>
